Reactor Systems Engineer

Ocean Atomics•Bethesda, MD

1d•$110,000 - $240,000

About The Position

The Reactor Systems Engineer will define the arrangement of the primary system, build and run system-level thermal-hydraulic models, and design and analyze the system architecture across normal, transient, and accident conditions. Ocean Atomics is an American company designing, licensing, and assembling a standardized nuclear electric power plant and the surrounding support systems for maritime applications. We will install these plants on any vessel built to our nuclear-ready standards, and will provide end-to-end sustainment in our planned nuclear lifecycle dockyard. We will help develop the licensed operators to unlock this new capability for your energy intensive application at sea. To move fast and to lead the creation of this new market, we are leveraging the compact, proven systems enabled by water-cooled reactors.

Requirements

Experience building and running system thermal-hydraulic models of nuclear plants
Strong understanding of primary system behavior, including natural circulation, two-phase flow, and the design tradeoffs between active and passive cooling
Working knowledge of decay heat removal design and the design basis events that size it
Strong working knowledge of one or more reactor systems codes (e.g. RELAP5-3D, TRACE)
Ability to work on a close, rapidly iterative design team and translate analysis into arrangement decisions
Strong technical writing skills

Nice To Haves

Bachelor's degree in Nuclear or Mechanical Engineering
5+ years designing or analyzing reactor primary systems
Familiarity with multiple system and subchannel/CFD tools (e.g. RELAP5-3D, TRACE, GOTHIC, COBRA, STAR-CCM+) and with coupling system models to neutronics
Experience supporting safety analysis and licensing basis development (DBAs, LOCA/non-LOCA, station blackout)

Responsibilities

Define and maintain the arrangement of the primary system and its interfaces with supporting systems
Build, run, and maintain system thermal-hydraulic models spanning steady-state, transient, and accident scenarios
Design and analyze decay heat removal architectures and demonstrate adequate cooling for limiting events, leveraging the maritime environment as appropriate
Support trade studies that balance arrangement, component sizing, and safety margins
Rigorously document analysis results and justify methodology and V&V in support of the licensing process
Couple system models with neutronics and structural inputs to support multiphysics and transient studies
Provide primary system and accident-response information to safety analysis, simulator, and operations teams
